質問 # 18
You want to keep virtual networks isolated from each other within the Juniper Apstra system. In this scenario, what are three ways to accomplish this task? (Choose three.)
正解：A、B、E
解説：
To keep virtual networks isolated from each other within the Juniper Apstra system, you can use one or more of the following methods:
Enable Security Policy for virtual networks in the same Routing Zone. This allows you to define rules that control the traffic flow between different virtual networks within the same routing zone.
You can specify the source and destination virtual networks, the protocol, the port, and the action (allow or deny) for each rule. The security policy is applied on the ingress interface of the leaf devices.
Use Connectivity Templates to block access within the same Routing Zone. This allows you to customize the connectivity between different racks within the same routing zone. You can create templates that define the link type, the routing protocol, and the access control list (ACL) for each rack pair. The ACL can be used to filter the traffic based on the source and destination IP addresses, the protocol, and the port.
Put each network in different Routing Zones. This allows you to create logical boundaries between different virtual networks based on the route target (RT) values. A routing zone is a collection of virtual networks that share the same RT for importing and exporting routes. Virtual networks in different routing zones do not exchange routes with each other, unless you configure remote EVPN gateways to connect them.
質問 # 19
You have designed your fabric in Juniper Apstra prior to deploying the network devices. Which Apstra element in the Staged tab would be used to assist the team that is installing and cabling the devices?
正解：B
解説：
The Links table in the Staged tab shows the physical connections between the devices in the fabric. It provides information such as the source and destination device names, hostnames, serial numbers, roles, interfaces, and link status. The Links table can be used to assist the team that is installing and cabling the devices by verifying that the devices are connected correctly and that the links are operational. The Links table can also be used to troubleshoot any connectivity issues that may arise during the installation process.
質問 # 20
Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)
正解：C、D
解説：
The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
The output shows a LAG connection. This is true because the interface node has a property called lag_mode which is set to lacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters.
The switch in the output is a Juniper device. This is true because the interface node has a property called if_name which is set to ae, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces.
The interface has an IP address assigned to it. This is false because the interface node has properties called ipv4_addr and ipv6_addr which are both set to null, indicating that the interface does not have any IPv4 or IPv6 address configured.
The interface has tags assigned to it. This is false because the interface node has a property called tags which is set to null, indicating that the interface does not have any tags associated with it.
質問 # 21
You are attempting to attach the server connected to the my_border_001_leaf1node's ge-
0/0/5 interface to the finance-appvirtual network.
Referring to the exhibit, what would you do to solve the problem?
正解：B
解説：
The ge-0/0/5 interface is missing from the Tagged VxLAN assignment list, which indicates that Apstra does not recognize a system (such as a server or appliance) connected to that port.
In Juniper Apstra, to enable a virtual network to be attached to a specific interface, that interface must be associated with a known endpoint - typically a Generic System.
By adding a Generic System to the physical topology and mapping it to ge-0/0/5, Apstra will recognize that interface as a valid target for virtual network connectivity templates, such as the one for finance-app.
質問 # 22
You are asked to deploy a collapsed fabric architecture. Which two statements are correct about this deployment? (Choose two.)
正解：A、C
解説：
In Apstra, a collapsed fabric (also described as "spineless") consolidates traditional fabric tiers so that the primary fabric devices perform combined roles. Instead of a dedicated spine tier providing transit between leafs, the fabric is formed by leaf devices connected directly to each other using mesh links. This means a collapsed fabric uses a full-mesh topology at the leaf level, replacing the usual leaf-to-spine connections found in a three-stage Clos. Therefore, the statement that leaf devices are full-mesh connected is correct.
Because the collapsed fabric devices serve the fabric roles, they also provide the EVPN-VXLAN overlay functions (VTEP behavior, EVPN control-plane participation, and VXLAN encapsulation/decapsulation) necessary for tenant segmentation and service delivery. Juniper's collapsed fabric validated designs further describe the collapsed fabric switches as serving all fabric roles (including border-leaf behaviors when external connectivity is required), reinforcing that overlay functions reside on these fabric leaf devices.
The remaining statements are not generally true for the collapsed fabric definition. Top-of-rack (access) switches-when present in certain collapsed designs-are not defined by default as full-mesh connected, and VXLAN support is not a requirement for those TOR/access switches unless the specific architecture explicitly uses them as VTEPs. The defining characteristics are the consolidated fabric roles and the leaf-level full-mesh.
